Final answer:
Friar Lawrence suggests that Juliet should wait another two years before marrying Paris.
Step-by-step explanation:
The character that suggests Juliet should wait another two years before marrying Paris is Friar Lawrence. In Shakespeare's play Romeo and Juliet, Friar Lawrence is a trusted advisor to both Romeo and Juliet. He performs their secret marriage but later advises Juliet to take more time before marrying Paris, as she is already married to Romeo. Friar Lawrence's advice ultimately leads to a chain of events that culminates in tragedy.
